Symmetricom 58517A 05Q GPS 1:8 Input 8-Way Active Signal Splitter w/ Ext Power [Refurbished]
( 362531940060) )
Model 58517A-05Q • DC Power Input Option • Excellent Used Condition • Guaranteed • 8 Way N Connectors
Item is very lightly used, in very good cosmetic condition. This is the 05Q version which allows for the antenna power to be applied by the connector adjacent to the antenna jack. My understanding is that if your antenna is powered (which almost all are) then you need to apply that power via the SMC connector adjacent to the antenna jack. Power sent from receiver(s) will not be passed through the splitter. This is a multiple item listing and while there will be very small cosmetic differences between units, the photos are representative of the item you will receive. No printed manual is included but a copy may be downloaded here if required.
Symmetricom’s Active Splitters allow multiple GPS receivers to share a single antenna. Designed for both manufacturing and position/timing redundancy applications, GPS L1 Active Splitters provide dependable signals for multiple GPS receivers.
For large manufacturing facilities, Symmetricom Active Splitters can provide as many GPS-L1 (1575.42 MHz) signals as your manufacturing floor requires. With built-in amplification to overcome splitter losses, the Active Splitters can be conveniently cascaded without adding separate amplifiers and bias-tees between splitters.

High Isolation Eliminates Receiver Interactions
Symmetricom GPS Active Splitters have the essential port-to-port isolation required to eliminate interaction between multiple GPS receivers. Without such isolation, local oscillator (LO) leakage from one GPS receiver can prevent other receivers from acquiring time and position signals and maintaining lock. In wireless base station applications, poor isolation can disable cell sites. In GPS manufacturing tests, poor isolation causes repeatability problems which can reduce yields and cause false rework.
Convenient DC Power Simplifies Your Installation
Power is conveniently obtained from the GPS receiver(s) connected to the amplifier. This eliminates the need for a separate dc power supply and wiring. DC power applied to the splitter is also passed on for use by an active antenna, further simplifying your installation.
